Definitions

  • the invention relates to a method according to the preamble of patent claim 1.
  • the invention further relates to a folding machine according to the preamble of patent claim 4.
  • a folding method or a folding machine of the type mentioned is known from DE-U 85 17 513. It is provided here that the workpiece receptacles receiving the partial shells can be rotated about an axis running in the plane of the parting line and that movable folding robots are arranged to the side of the workpiece receptacles parallel to their axis of rotation, the tool inserts of which have their own drive which progresses in accordance with the folding course in one direction of movement.
  • the folding tool is designed like a pair of pliers and the fold is thus progressively generated by alternating opening and closing and laterally moving the folding tool. The rotatability of the workpiece holders enables the successive production of two opposing folds with a folding tool.
  • a disadvantage of this known folding machine is its time-consuming, cyclical operation, which has a relatively low productivity.
  • only straight folds can be produced with this folding machine; the folding robot would have to be used for the production of more complicated folds get at least one additional direction of movement, which would significantly increase the design and control effort.
  • the new process and the new folding machine offer the advantage of a continuous operation, since the fold is generated by a rolling process. Furthermore, several fold passes are easily possible, which means a high quality of work can be achieved, even if e.g. B. stainless steel sheet is processed. Another important advantage is that the shape of the workpiece and thus the course of the fold can vary within wide limits; it is Z. B. easily possible to process non-circular, non-rotationally symmetrical workpieces, since the folding roller is able to perform a movement following the contour of the fold. Concave radii can even appear on the workpiece as long as their radius remains larger than the radius of the folding roller.
  • the fold also does not have to lie in the plane of the greatest extent of the workpiece, since the fold roller on a fold arm can be guided laterally from the outside to the workpiece and itself requires very little space.
  • the new method and the new folding machine can thus be used in a variety of ways and also allow the production of fold connections which run in a complicated manner, wherein the folding roller can be guided by the fold itself or by separate guide means.
  • a development of the invention accordingly provides that a guide roller is mounted on the free end of the folding arm to the folding roller, at least in its axial direction, which is also about an axis of rotation relative to the workpiece parallel axis is rotatable and runs during the folding process on a guide surface or curve, which is formed as part of one of the workpiece holders.
  • a guide for the folding roller is created in a simple manner, which makes the folding process independent of the properties and of dimensional and shape fluctuations of the folding flanges of the workpieces.
  • the method and the folding machine offer the possibility of regions of the workpiece in which the fold is interrupted by appropriate training, e.g. Easy to run over the guide surface and then continue the folding process without any other control measures being required.
  • appropriate training e.g. Easy to run over the guide surface and then continue the folding process without any other control measures being required.
  • an increase in the guide surface can be provided in the folding area projecting outwardly from the workpiece parts.
  • the first exemplary embodiment of the folding machine 1 shown here has a machine base 10 in which a drive and gear unit 11 is accommodated.
  • a total of four parallel guide columns 12, 13, 14 and 15 extend upward from the machine base 10.
  • the guide columns 12 to 15 are connected to one another by means of a yoke 17.
  • a pressure plate 16 is arranged, which can be raised and lowered along the guide columns 12 to 15, as indicated by the movement arrow 16 '.
  • the lifting and lowering of the pressure plate 16 is accomplished by a lifting cylinder 34, which is centrally attached to the yoke 17.
  • the associated piston rod 34 ' extends from the cylinder 34 downwards to the pressure plate 16, where it is connected to it.
  • a main spindle 2 which can be rotated by the latter, extends upwards.
  • the main spindle 2 carries a first tool mounting flange 2 ', which here has the shape of a flat cylinder and is arranged concentrically with the main spindle 2.
  • a printing head 3 is provided below the printing plate 16, which can be raised and lowered together with the printing plate 16, but can be rotated relative to the latter.
  • the print head 3 carries at its lower end a second tool mounting flange 3 ', which, like the first, lower tool mounting flange 2', has the shape of a flat cylinder.
  • the print head 3 and the associated tool mounting flange 3 ' are also concentric with each other and in alignment with the main spindle 2.
  • the lower tool holder flange 2 'and the upper tool holder flange 3' each carry a workpiece holder 20 or 30, which are designed as interchangeable tools, each adapted to a workpiece to be machined, and are preferably screwed to the tool holder flanges 2 'and 3'.
  • the two workpiece receptacles 20 and 30 are each formed here with a bowl-shaped recess 21 and 31, each of which for the form-fitting reception of a half-shell of a workpiece to be machined, eg. B. a shell muffler formed from two half shells or partial shells, serve.
  • the inside of the workpiece receptacles 20 and 30 are preferably provided with a plastic lining which consists of a pourable, low-elastic hardening plastic.
  • the inner contour of the cup-shaped depressions 21 and 31 in the workpiece receptacles 20 and 30 can thus be produced with a precise fit by pouring the plastic in liquid form, pressing in a sample of the workpiece or the associated partial shell and allowing the plastic to harden.
  • the division plane of the two workpiece holders 20 and 30 coincides with the division joint or plane of the two partial shells of the workpiece to be machined.
  • the two workpiece receptacles 20 and 30 each have a circumferential fold surface 22 and 32, which serve as pressure surfaces during the folding process.
  • the lower workpiece holder 20 has a circumferential guide surface 23 below its folding surface 22, which, as will be explained later, can have different radial distances from the folding surface 22.
  • FIG. 1 is shown in FIG. 1, which is arranged here to the left of the workpiece holders 20 and 30.
  • the folding arm 4 is designed as a pivotable arm which is mounted in a pivot bearing 41 on the guide column 14 arranged on the left in FIG. 1.
  • the folding arm 4 carries a guide roller 43 which rolls on the guide surface 23 of the workpiece holder 20 during the folding process.
  • a folding roller 42 is arranged above the guide roller 43 and is also set back somewhat with respect to the guide roller 43, ie offset to the left in FIG. 1.
  • This folding roller 42 runs during the folding process with the interposition of the folding flanges of the workpiece to be folded on at least one of the two circumferential folding surfaces 22 and 32 of the workpiece holders 20 and 30.
  • the pressing force of the folding roller 42 in the direction of the workpiece receptacles 20 and 30 required for the folding process is generated here by a pressure cylinder 44, which in turn is pivotable on the one in FIG. 1 left front guide column 12 is mounted in a bearing block 45.
  • the pressure cylinder 44 is preferably operated in the folding machine 1 so that it exerts a constant force regardless of the position of its piston or its piston rod.
  • FIG. 1 In the embodiment of the folding machine shown in FIG. 1, it only has a single folding arm 4; for practical use of the folding machine 1, however, it is expedient to equip the machine 1 with a pair of two identical folding arms 4 or even several pairs of the same folding arms 4.
  • FIG. 2 shows an embodiment of the folding machine 1, in which it is equipped with a pair of two mutually identical folding arms 4.
  • the two folding arms 4 and the machine base 10 are shown in a top view and the four guide columns 12 to 15 are shown in section.
  • the parts of the folding machine 1 that are still present below the folding arms 4, in particular the workpiece holder 20, are not specifically shown here.
  • each of the two folding arms 4 has a substantially rectangular L-shape with a longer L-leg 40 and a shorter L-leg 40 '.
  • the longer L-leg 40 is formed at its outer end as a pivot bearing 41 and pivotally mounted on the associated guide column 14 or 15, as indicated by the movement arrows 41 '.
  • the shorter L-leg 40 ' carries at its free inner end a folding roller 42 or 42' and a guide roller 43.
  • the two guide rollers 43 are the same here, while the folding rollers 42 and 42 'preferably have different profiles.
  • the roles 42, 42 'and 43 are each rotatable about axes that run parallel to the workpiece axis of rotation 5 '.
  • the already mentioned pressure cylinders 44 are used, which run at an acute angle to the respectively shorter L-leg 40 '.
  • the cylinders 44 are each mounted in a pivot bearing 45 'on a respective bearing block 45, which in turn is rigidly connected to a fixed part of the folding machine 1, here the guide column 14 or 12.
  • the piston rod of the cylinder 44 extends from the bearing block 45 inwards to the vicinity of the inner end of the shorter L-leg 40 '.
  • an adjusting cylinder 46 is provided on each folding arm 4, which serves to adjust the folding roller 42 or 42 'in position relative to the guide roller 43. So that the position of the folding rollers 42 and 42 'for different runs of the folding process can be changed gradually to carry out the folding process step by step. There is also the possibility, with different profiling of the folding rollers 42 and 42 ', to begin the folding process with the first folding roller 42 and after a corresponding further rotation of the workpiece about the workpiece rotation axis 5', the second folding roller 42 'can be used.
  • the two folding arms 40 are arranged offset from one another by approximately 90 ° about the workpiece axis of rotation 5 '.
  • This arrangement has the advantage that in the case of workpieces whose fold forms a geometrical outline with very different semi-axes, the folds on the workpiece men 4 generated torques are at least partially offset against each other.
  • the folding arms 4 extend from the pivot bearing 41 in the workpiece rotation direction and are then angled inwards towards the workpiece axis of rotation 5 '.
  • FIG. 3a An example of a workpiece 5 which can be processed with the folding machine 1 described above is shown in a top view in FIG. 3a.
  • the view falls on the upper shell 50 of the workpiece 5, which has an outwardly projecting flange 51, which is interrupted in two areas by a pair of pipe connections 52.
  • the lower shell 50 'of the workpiece 5 which in turn also has a projecting flange 51' which runs parallel to the upper flange 51, but has a smaller width.
  • the lower, the lower shell 50 'of the workpiece 5 fittingly receiving the lower workpiece holder 20 can be seen in partial areas of FIG. 3a, more precisely its circumferential guide surface 23.
  • the guide surface 23 runs parallel in the region of the folded flanges 51 and 51' offset to these inwards.
  • the guide surface 23 is designed to be elevated, ie it projects outward beyond the outer boundary of the pipe connections 52. It is hereby achieved that the folding rollers on the folding arm are lifted off the workpiece 5 by the guide roller 43 rolling on the described guide surface 23 in the region of the pipe connections 52, that they run past the pipe connections 52 without contact. In the other areas of the workpiece 5, however, the folding process is carried out with constant rotation of the workpiece 5 about its workpiece axis of rotation 5 '.
  • the assignment of the two partial shells of the workpiece 5, namely the upper shell 50 and the lower shell 50 'to each other is clear.
  • the upper shell 50 and lower shell 50 ' lie with their mutually parallel folding flanges 51 and 51' on top of each other and are pressed firmly against each other by means of the end faces of the partially visible workpiece holders 20 and 30.
  • the upper rabbet flange 51 of the upper shell 50 has a greater width, i. H. a larger extension to the outside than the lower rebate flange 51 'of the lower shell 50'.
  • the circumferential rabbet surface 22 and the circumferential guide surface 23 can also be seen on the lower workpiece receptacle 20.
  • FIGS. 4a and 4b and 5a to 5c The method and the mode of operation of the folding machine 1 are explained below using two exemplary work processes according to FIGS. 4a and 4b and 5a to 5c:
  • the upper and lower shells 50 and 50 'of the workpiece 5 are inserted into the two workpiece holders 20 and 30, the upper workpiece holder 30 being raised upwards by means of the lifting cylinder 34.
  • the upper workpiece holder 20 is lowered by means of the lifting cylinder 34 and with a sufficiently large one Contact pressure pressed against the lower workpiece holder 20.
  • the projecting flange 51 and 51 'of the workpiece 5 are pressed firmly against each other, so that mutual displacements are practically excluded.
  • the main spindle 2 is rotated by means of the drive and gear unit 11.
  • the two workpiece holders 20 and 30 are also rotated together with the workpiece 5 located therein.
  • the folding arm 4 or one of the folding arms 4 is pivoted up to the workpiece 5 until the folding roller 42 or 42 'is present with a sufficient pressing force on the folding flanges 51 and 51'.
  • a pre-folding takes place, the upper folding flange 51 being folded downwards and inwards by means of the first folding roller 42.
  • the pre-folding can be done in one or more passes, i.e. H. Revolutions of the workpiece 5 take place.
  • the folded flange 51 'of the lower shell 50 initially remains undeformed.
  • the second folding roller 42 ' is then brought into contact with the folding flanges 51 and 51' in the first sequence example, whereby the final folding of the folding flanges 51 and 51 'takes place to the finished fold 53 in which the individual layers of the fold 53 are fixed lie on one another.
  • FIGS. 4a and 4b show, two very differently profiled folding rollers 42 and 42 'are required in this example of operation, of which the first folding roller le 42 can only take over the pre-folding and the second folding roller 42 only the pre-folding.
  • the folding rollers 42 and 42 'used here can each be used for two folding processes.
  • the first folding roller 42 is also used to pre-fold the upper folding flange 51 downwards and inwards, the lower folding flange 51 'still remaining undeformed.
  • the upper folded flange 51 is folded over further inwards, the lower folded flange 51 'also being folded over downwards.
  • the folding process for producing the finished fold 53 is completed according to FIG. 5c, here either the folding roller 42 or the folding roller 42 'or both folding rollers 42 and 42' can be used synchronously.
